from Oil-Distillation Resid-uum; and I do hereby declare the'following to'be a full,

, in the process of oil distillation and conscquently intermixed with carbon and the heavier oils incident to carrying out my distillation process, which latter has been duly described and claimed in the Letter Patent granted to me.

The main object, therefore, of my invention, among others, is to provide means for completely freeing the lime fromcarbon, heavier oils, etc, and my invention, with this object in View consists of certain novel features of combination and construction of parts which will be hereinafter clearly set forth in the following specification, illustrated in the accompanying drawings and pointed out in the ClZL'lIIISL' Other objects and advantages of'my invention will be hereinafter made clearly apparent.

Reference being had to the accompanying drawings, which are made a part of this application, in which,

Serial No. 65,736.,

providing a suitable form of furnace designed primarily, as' stated, for the reclamation of lime after it has been used in the distillation of oil andQmeans for introducing air at the changing point of combustion, as will be necessary as the mass of combustible material is increased or diminished.

Referring in detail to the various features of my invention and parts necessary to cooperate therewith, l designates the furnace walls made of any suitable material and erected upon a proper form of base or support and provided with any preferred form of grates 2 having suitable controlling lever 3 therefor, whereby the grates or any section thereof may be readily shaken to dis charge the accumulated lime thereupon. I

Extending into the combustion chamber 4 thus or otherwise provided, I prefer to provide the pipe sections or tubular mem-' bers 5, each having a plurality of air discharging ducts or slotted apertures 6 extending from near the top thereof to their bottom ends, which latter are designed to rest directly and securely upon one of the cross bars or equivalent device, it being understood that there may be any preferred number of the pipes or tubular members5 as may be indicated as desirable to produce the best results. Obviously the tubular sections 5 may be round or square in cross section, though I have shown the same of the latter form, and designed to move longitudinally within each of the tubular secti0ns 5, I provide the plungers or closures 8, one for each tubular section 6, and all preferably connected together as by suitable frame Work 9 whereby all may be simultaneously raised or lowered by any suitable means, as by the connecting chains -10, pulleys 11 and controllinlg'cable12 or other suitable means; The lower ends of the tubular members 5 are placed directly in communication with the air supplying pipes 13 and inasmuch as theislotted apertures G are provided throughout the length of the tubular members 5, it follows that by raising or lowering the closure members or plungers 8, the said ducts or slotted openings 6 may be wholly closed or any number, thereof may be left open for the admission of air from the pipes 13 as will be clearly apparent.

It will be understood that the pipe sections 13 may be placed in connection with any suitable form of blower or fan whereby lot :40 carrying out my oil 45 26 may also be W65 feet operation of the bustion chamber,

60 necessary the requisite degree of draft may be af forded to insure perfect combustion. In order to provide convenient means whereby the fuel may be readily supplied to the com I provide the opening 14: in the upper part of the furnace 1 and over said opening, I locate the conveyor chute 15, and mounted within said conveyer chute, I provide an endless carrier consisting of; suitable sprocket chains or equivalent 16, passing over suitable pulleys upon the axle 17, the said chain being provided with a plurality of transversely disposed cleats or bars 18 and it is obvious that the said endless car-- rier will convey any material placed thereon and delivei' the same into the opening Li, Which latter may be easily closed or opened by means of the controlling lever 19 pivoted at the fulcrum point 20 and properly con 20 nected with the sliding cover 21 as Will be readily apparent. In like manner, I have provided beneath the furnace a similar endless carrier, the parts of which are designated by the same numerals employed in the description of the delivery chute l5, and as a similar chute or trough-like member 22 is provided beneath the furnace, it is obvious that when the lime which has been freed of carbon, oil or the like, is deposited Within 3o the chamber 23 by an agitation of the grate bars 24 through the mediation of the con trolling levers 25, it follows that the re claimed lime Will he delivered into the chute '22 and thence carried to any point desired by the endless carrier located therein.

Y'Vhile, primarily, my object is the reclamation of the lime, as stated, yet incidentally I also produce a high degree of heat Which I am enabled to effectively employ in distillation process, as by delivering the products of combustion, including any' unconsumed gases, directly into the fire box of my retort,it being under stood that the perforated gas pipe or burner provided in the pipe box and supplied With any suitable source of thereby insuring" the complete combustion of Zi any'gases that may be delivered from my improved furnace, as will be obviously It will furthermore be readily apparent that my improved furnace may be operatively connected to or placed in coiiperation. with any preferred number of retorts,

whereby the heat from my furnace may thus Yeration of reclaiming the lime an intimate (to-acting part of the distillation process, inasmuch as the fuel supplied by my retort -\vhen used in my furnace, will produce the rcqui'sitedegrec of heat required for the perretort, thus establish ing a' substantial interdependence of the process of reclaiming the lime, and the proc' ess of oil distillation, wherein lime is used in connection With the oil.

Inasmuch as a relatively large quantit of lime is employed in my oil distillation process, it becomes very important'and desirable that such lime be reclaimed in order that it may be used over and over again, and it will be clearly apparent that owing to the high degree of heat which I am euabled-to produce Within my furnace, the carbon and heavier particles of oil remaining in the lime will be completely released by the assured perfection of combustion in (admit to the supply of air at the combustion point, thereby permitting the free or recovered lime to drop downward upon the grate bars Wholly free from impurities and ready for reissue. It is also obvious that since the free lime will. drop down upon thegratc bars in. a compact mass, it Would be impossible to introduce the requisite quantity of air to the combustion point, were it not for the means, which I have illustrated, comprisin; thctubular members 5 having a plurality of air delivering;- ducts or slots and n'ieans to tightly close all of said ducts 'at will above the comlmstion point, leaving only those ducts open which are still in the mass of flames, or at the combustion point.

It is obvious that further means may be employed for introducing air at the exact point of combustion and to change the air at a point to coincide with any change in the change of the position of the burning mass of material, and I, therefore, Wish to comprehend and claim in this application, any suitable means whereby the introduction of air may be accomplished and the air delivered at gny desired or changing point Within the furnace. 7

Obviously as the quantity of reclaimed lime increases in the lower portion of my furnace, the combustion point for the mass of unfreed lime, mixed with carbon, oil and the like, delivered above the free lime will gradually rise higher and higher, thereby making it necessary to gradually raise the plungers or closures 8, point will be raised, thequantity of burning material is increased, it being understood that the lower openings for the air become closed by the accumulation of reclaimed lime.

In the present application, I have shown but one retort'placed in coiiperation with my furnace, both beingsubstantially on the same floor or level, but it will be understood that my improved furnace may be properly connected with any preferred number of retorts, or my form of furnace may be located directly below the retort in Which case the products of combustion will so that the air exit 1,1ee,eee

reach. directly ineontoct with my retort and best the to the requisite degree.

Believing that the construction and mannor of using my invention is thus made clearly apparent, further description is deemed oi ssery.

What l claim and desire to secure by Letters l e-tent is: v

1. A iuuecelor the recovery of lime from carbon, oil and the like comprising a suitable combustion chamber, grate bars, and means to operate said em, and air supplying slierts having a, plurality of perforations, supply pipes communicating with the lower ends thereof and closures for said supply pipes adepted to be raised or lowered at will, and means todeliver the fuel supply throughout the upper portion of the furneoe. I

2, A furnace forthe reclamation of lime from cirbou oil and the like, consisting of a combustion chamber, suitable grate bars therefor in combination with air supplying shafts provided with a plurality of perforations or slotted openings on each side thereof, supply pipes for introducing air into the lower ends of said shafts, and

'2nesns to open or close any preferred open ings Within said shalt whereby the air Will be supplied directly to the burning mess of materiel o Lliin the combustion chamber without reference to the change of position of said burning mass.

3, A furnace for recovering lime from carbon, oil the like, consisting of a furnace proper having a suitablev combustion chamber and controllable grates therefor, of a plurality of air introducing pipes end to withdraw the recovered lime from the lower portion thereof.

4. A furnace ior reclaiming lime from evil carbon and the like, comprising s combus carbon, oil and-the lilre ondmans to introduce air under any desired pressure into the bottom and at plurallty of polnts throughout the burning mass Without reference to any change in the position of said burning mess.

In test1mony whereof I have signed my name to tins specification.
